Conditional formatting based on a checkbox

Good afternoon. 

 

I wonder if someone can help me please :-) 

 

I have a spreadsheet that has rows of client data, what I am trying to achieve is when I click the checkbox it turns the row green. I have researched it and all the info look different to the conditional formatting I can see, I am using  Excel 365 web based excel I don't see the the option 'Use a formula to determine which cells to format.' 

 

I see apply to:  and Format Cell where the formula is true can someone please help

 

Thanks Joel

    In my online / web interface here is my Conditional Formatting (add new rule) window:

    notice the Fx all the way to the right, that is the use a custom formula.

    then you just need to use a formula like

    =$A1

    where the $A needs to be the column where the checkbox is, and

    the 1 needs to match the first row in the "Apply to:" range
